Legio XIV Gemina

Legio XIV Gemina was a legion of the Roman Army which was levied by Julius Caesar in Cisalpine Gaul in 57 BC before the Gallic Wars. It was combined with another understrength legion after the Battle of Actium in 31 BC, earning it the nickname Gemina ("twinned"). It fought in Pannonia in 9 AD, in Germanicus' campaigns against Arminius in Germany, in the invasion of Britain in 43 AD, in Boudicca's revolt in 61 AD, and in Trajan's wars with the Sarmatians and Dacians. The legion was based at Carnuntum for three centuries after the Dacian wars, and it proclaimed its commander Septimius Severus as emperor in 193 AD. During the Crisis of the Third Century, Legio XIV Gemina fought for the Roman emperor Gallienus against the Gallic Empire, only to defect to Gaul after Gallienus' death. The legion was finally dissolved after the collapse of the Danube frontier in the 430s AD.
